LJ Lock-N-Load Long-Arm Suspension System, 4.5"/6"

Product ID: 7143*
The Jeep LJ Wrangler Lock-N-Load Long Arm Suspension provides great road manners and maximum articulation for off-road; it is the only Long Arm system that has bind-free front radius arms with the use of the Patented MetalCloak Lock-N-Load upper control arm. (metalcloakpatents.com)

Highlighted system features are:
  • Front Lock-N-Load™ Radius Long Arm
  • High-Misalignment (NVH) Duroflex™ Control Arms
  • True Dual Rate™ Coils
  • Front & Rear Durotrak™ Bushing equipped track bar
  • Track Bar weld on bracket
  • 3 Piece High Clearance belly pan
  • Adjustable bump stops
  • Drop Pitman Arm
  • 3 layer Stainless Steel extended Brake lines
  • Shock mount brackets
  • Made in the USA
The Patented Lock-N-Load Radius Long Arm eliminates [click for more...] bushing bind and unleashes the full capabilities of the system without losing the safety of 4 contact points on the axle.

True Dual Rate™ Coils provides the most comfortable and stable ride over traditional single rate lift springs, and provide better load handling than the typical "progressive/multi-rate" coils. Our True Dual Rate coils are extra long in free-length to maintain contact for extreme articulation. MetalCloak has over a decade of proven dual-rate coil performance.

The Durotrak bushings reduce NVH (noise, vibration and harshness) that can be transferred to the driver and provides a smoother ride while also improving the vehicles steering input. The patented bushing is a 2-part design that can rotate 360 degrees in a vertical plane unhindered while minimizing horizontal forces to keep the Jeeps axle centered and you going in the right direction.

3 Piece Belly Pan is designed for abuse and engineered to be the best. Front and rear departure and approach angles, boat sided, solid design stiffens the chassis, clearance for stock or aftermarket transfer case, and the center section may be removed to allow servicing of protected components.

We offer a choice in shocks; run the shock set-up you choose to fit your build needs. If you have a different idea of what shocks will work best for you- go for it. MetalCloak suspensions ARE designed to optimally be used with the patented MetalCloak 6Pak™ Shocks for maximum up and down travel. Our RockSport Shocks (Exclusively at MetalCloak) provide the next longest travel you can get with the simplicity of a standard shock and share the same valving as 6Paks; this is a great option if looking for a no-maintenance option at a great price. The choice is yours to buy the suspension with or without shocks; we recommend our specifically tuned shocks but we leave the choice up to you.

Adjustable height front and rear bump stops are a MetalCloak first and allow you to adjust the travel to be tailored to the size of tire you have optioned for. Add more bump stop or remove to adjust to the clearance you need without having to remove the coils.

Every aspect of clearance has been taken into account with angles and skids built into the carefully developed components. Weld-on and bolt-on pieces transform the Jeep Wrangler into a well-mannered street driving machine and an all-out high-performance rock crawler for off-road.

MetalCloak “components” have been proven safe with the FMVSS certificate of safety configured with 37inch tires, full body armor and suspension lift.

Note: This Kit Requires Welding at the rear axle.

Note: MetalCloak does not recommend powder coating your True Dual Rate Coils. See instructions for additional details.

Note: We Recommend You Have a Suspension Specialist Align Your Jeep Once a MetalCloak Suspension is Installed.

Note: This item is being offered as a complete system that contains all the components shown. We cannot customize, replace or remove a component from the kit. If you need a custom order, all components are available individually and our sales team is happy to help you place your order.

Note: If you purchase this system, and decide you do not need a component or part of the system, we cannot accept returns. [click for less...]

Who Is MetalCloak?

MetalCloak creates Game-Changing Products for the Off Road Enthusiast.

Duroflex Joint Revealed

The MetalCloak Duroflex Joint takes the best qualities of OEM style Clevite Joint and the popular Johnny Joint style Flex Joint and combines them.

Vibration Dampening

We tested our Duroflex Joint using a "Shaker Table" and seismometer app to show how much Vibration Dampening the Duroflex Joint gives you compared to other industry leading joints.

A Comparison of Flex

Comparing the Flex of the Duroflex Joint with that of the Johnny Joint, the Teraflex Monster and the typical Clevite.

Lock-N-Load

"Typical" Radius Arm systems inherently bind causing premature bushing wear and excessive stress on bracketry. The Lock-N-Load solves that problem.

Coil Springs 101

This short video covers all you need to know about the basics of how typical Coil Springs work compared to MetalCloak's True Dual Rate Coils.

Durotrak™ Bushing

Eliminate squeaks and clunks in your steering with the technology of MetalCloak’s Durotrak™ bushings; exclusively found in MetalCloak track bars.

FMVSS 126 Compliant

MetalCloak not only has the best off road flex, but we are also Federal Motor Vehicle Safety Standard 126 certified and compliant. No other company can match our on- and off-road performance.

THE TECH

Metalcloak Suspension System

So what's in the kit?

  • Front Lower Long Arms
  • Lock-N-Load
  • Front Upper Radius Control Arm
  • Rear Long Arms
  • 3 Piece Belly Pan Skid
  • Front & Rear True Dual Rate™ Coils
  • Front & Rear Durotrak™ Track Bars
  • Front Weld On Track Bar Bracket
  • Front & Rear Adjustable Bump Stops
  • 3in Pitman Arm
  • Front & Rear Extended Brake Lines
  • Front & Rear Sway Bar Links
  • Shock Mounts

IT ALL STARTS WITH THE BUSHINGS

The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a bolt-on suspension kit. Period.

Duroflex Control Arm Joint Comparison

MetalCloak has taken the best features of the most widely used control arm joints and combined those features to create the Duroflex Joint, producing a Low-Maintenance, High-Misalignment (34˚), Self-Centering, Rebuildable Joint with an OEM quality ride.

Duroflex Kevlar Bushing

Now with Kevlar!

DuPont™ Kevlar® Fiber is now compounded in the proprietary elastomer of the Duroflex Bushing, bringing even more strength, durability and performance.

Kevlar® is a synthetic fiber with extremely high tensile strength to weight ratio…five times stronger than steel and commonly used in bullet proof armor applications.

Duroflex Bushings w/Kevlar® can be identified by the Metalcloak “M” located on the outer surface.

Control Arm Duroflex Joint Alignment...

At MetalCloak we take the care to build every product right.

Most manufacturers build their control arms misaligned from center. Why? It simply costs less to do so.

By not cutting any corners, our joints are Centered and Aligned reducing wear and improving performance.

It makes them easier to install, too!

Duroflex Misaligned

Lower Front Long Arms

TJ/LJ Lower Front Long Arms

Both the Front Radius Arms and the Lower Rear Hi-Clearance Arms are manufactured for the ultimate in strength and versality.

Lock-N-Load

MetalCloak's Lock-N-Load Radius Arm system removes the most common problem that causes more long term damage to bushings and axles... BIND.

The Lock-N-Load extends at full droop, compressing one spring and extending the other.

At full stuff, the Lock-N-Load compresses. There is always compression and resistence.

Lock-N-Load Compression

What About Daily Driving?

Once "Locked" the Lock-N-Load coils are fully compressed creating a rigid arm for increased stability in daily driving.
Lock-N-Load Locked Position
Lock-N-Load Loaded Position
In the "Loaded" position, the Lock-N-Load is ready to provide up to 1.5" of compression or extension for additional off-road articulation and to relieve stresses from bushings and brackets.

The 4-Link Rear Perfected

While the Radius Arm front was ideal, we realized the space in the rear allows for a properly engineered 4-Link.

Choosing the 4-link rear control arm design provides added torque strength support for the main drive axle and provides a fantastic overall ride quality.

Our design eliminated the typical unsteady "Long Arm Roll" felt on a lifted TJ/LJ while cornering - and that's without running a rear sway bar!

Degrees of Articulation

What are True Dual Rate Coils?

MetalCloak True Dual Rate™ Coils have one of the longest free length in the industry for greater articulation without sacrificing the OEM ride quality.


Without the advantage of the Dual Rate Design, the required Spring Rate would be too low and "squishy" -- just loading your Jeep up with supplies would affect ride height and quality. (Learn More About True Dual Rate Coils)
